Occasionally skimping on sleep for fewer hours won't shun your growth that much. Once it becomes a regular thing it will impact your height, especially in adolescence. When you sleep, your body releases Human growth hormone (HGH). The production of this hormone goes down when you fail to get a sufficient amount of shut-eye. Babies need more sleep than adolescents. As they grow up the requirements for sleep decrease. So, try to get an ample amount of sleep to stay fit and healthy.
